Flotation

Superior flow conditions inside the cell enable best results in dirt speck removal and increased brightness at lowest fiber loss. Efficient foam breaking. The foam generated in the primary cells is collected in the foam trays and discharged into the foam tank. The FoamEx foam breaker is located on top of the foam tank and destroys the foam mechanically by creating a partial vacuum through rotation
